To all whom it may concern:

Be it known thatjI, SAMUEL -HAMILTON HOGGSON, a citizen of the UnitedStates, and resident of the town of Arlington, county of Hudson, Stateof New Jersey, have invented certain new and useful Improvements in'Motometers, of which the following is a specification. v I

This instrument, which is the result of my experiment and invention, isfor the purpose of registering and recording the movement due to thevibration, sway or continued undulation of a body, or'anypart .thereofto which it is attached.

In construction the device is particularly simple though arranged forthe highest possible eliiciency, and its indicating portions are soarranged and ad uSted as to make the wholeextremelyi sensitive, thus itwill be effective even where the shock is I slight.

My instrument in the proper performance of its duties depends upontwo'forces, one of which I will call the positive or principal force isa known quantity and quality and is as near constant as it is possibleto make it. This force is used to impart to the several cylinders ordrums, and to'the other mechanically moving parts, their proper relativemotion. The other force is the one whichmy instrument is designed torecord. It is the sharp jar or vibration due to the motion of the bodyto which it is attached, or it may be simply themotionof one ofthe partsof the greater body, occurring at intervals of long or short duration,they will leave their impression permanently recorded .on a roll of tapeprovided for that purpose.

The apparatus can be used for a number of (liil'erent purposes, the maindrums or wheelsmay turn at difi'erent speeds and the printing wheel maylnscribe any series of characters on the tape, but I have used it verysuccessfully in conjunction with an or dinary time piece, such as aneight day clock for its positive driving means and I will so describeit. In this instance the type wheel prints the hour of thefd'ay andnight and malies one complete revolution every twenty four hours. andthe platen is so arranged that it will turn in unison with the typewheel. I have invented .new and simple means of securing the recordingneedle in its proper relative position, and have invented new and highlyefiicient means of im parting motion to theneedle. Many other novelfeatures I have added which will. be

fully described in the specification which follows The following is whatI consider the best means of carrying out this invention.

lhe accompanying drawings form a part of this specification, in which:

Figure, 1 is a front elevation. Fig, 2 is aside elevation correspondingto Fig. 1. Fig, 3 is a side elevation of the interior mechanism. Fig, 4shows the interior mechanism in front elevation. Fig, 5 shows in sideelevation a device of a somewhat different construction having the samegeneral principle. Fig, 6 1s a front elevation of the device shown InFig. 5. F 1g., 7 is an elevation of the side opposite to that shown inFig. 5.

Similar letters of reference indicate like parts 1n all the figureswhere they appear. ()ne of the principal members of my mechanism is theprinting wheel or drum shown at A. It is of cast metal preferably brassand at its periphery is provided with a deep circumferential groove a.Into the groove (1, a rubber band A is secured carrying a series ofprojections, upon the faces of which have been produced printingcharacters representing the twenty four hours of the day. The wheel Acarrying its band A is firmly secured upon a shaft A and convenientlyand securely located upon this adjacent type face upon a ribbon, or tapeof paper or other material which is passing over the wheel B. The tapeis supplied from a roll D convenient in size to furnish any desiredamount. I have in my experiment used a roll of about two inches indiameter, and have found this length to be suflicicnt to receive theprinted characters continuously for six months allowing sufficient forwaste during adjustments or resettings. The tape roll D is located inany convenient place relative to the Wheel B and is loosely androtatably mounted upon an axis D After the paper has passed over thewheel B and has received the 1mpression,-it passes beneath the shield Ethrough which the perforating needle G operates, then the paper is freeto fall down avard curling up in any convenient place which may presentitself.

That the printing type carried by the typeby having its periphery wellsaturated with r a special ink such as isused on the ordinary stamp pad.One of the most important members of my device is the needle G and themeans for properly operating it.

Referring to Figs. 3 and 4, the needle G is shown as mounted in a holderG, with convenience for a horizontal axial move v ment therein. It is ofsteel of a convenient size rounded and well polished and-the point G ismade small and sharp. The end of theneedle opposite the point, carries alarge head or button G which may be formed integral therewith or whichmay be a separate piece securely fastened in piace. A shaft H mounted-in thebearing 1 is free to revolve therein, it carries at one end thepart H which'is a nearly eomplete disk, but a small section hasbeen cutaway so as to produce a flat face to-Tbear fairly upon the button headGr of the needle G. Securely attached to the shaft H, to

the end opposite to that which carries the art H is a block H having atransverse iiole. The red I, which I will sometimes term the vibratingarm carries the hammer J at an extreme end, the other end is inserted inthe hole and fastened therein by the binding screw. On the rod I, ashort distance-from its junction with the block H a block K is fixed.Two blocks L and M in line-with each other, andvwith the block K arelocated at equal distances from the red I, one on each side thereof.Screwthreaded holes Z and m havebeen produced one ineaeh of the blocks Land M respectively, and a knurled-headed adjusting screw is insertedinto each of the screw- -threaded holes. Light coiled springs arestretched from these adjusting screws to the blocks K-and exert anapproximately even tension on each side insuring, that the red I, willtend to remain in a horizontal position. On the lower end of the uprightshaft 0 is a worm-gear O meshing with the gear A and a second worm-gearT meshes with the cut-gear 13 ,011 the shaft B On the upper end of theupright shaft O is a bevelgear R. I

The operation of my device and its separate parts is simple and ofallOlJVlOllS character, and yet I will describe it in detail as certainelements may develop which have not been fully described in thespecification. A source of positive and-continuous power as the clock Vis attached to the bevel-gear R driving it with a motion that will causeit to make one complete revolution each hour. The motion is transmittedthrough the worm-gears O and T, which in turn mesh with the gears-A and,B causing the shafts and drums mounted thereon, to make a completerevolution in twenty four hours. The gear A mounted on the shaft A is ofa corresponding size to the gear B, and has an equal number of teeththerewith. Mesh ing as it doeswith the gear T, it will make,

and cause the shaft and printing drum adjacent to make a revolutioncorresponding to, and in even time with a revolution of the Wheel ordrum B. The frictionof the type rolling against the'adjacent'. surfaceof the drum B will cause the strip of paper be-,

tween them to advance justso rapidly as acters from the printing, facesof the type. After the paper has received the impression it passes downbehi-nd the shield E and, if the body is at rest to which my instrumentis attached, "the paper falls into a coil below without furtherdisturbance.

But if the required to present freshsurface at even I d stance apart,for the reception of the charmachine is moved even to a small extent thehammer J moves. with an up and down motion turning the shaft H through aportion of a revolution, and the disk H mounted thereon actingthroughits flattened side,

imparts a horizontal motionto the needle G causing it to advancesufiiciently to.makea perforation, or if the motion be eontinu ous, .aseries of perforations in the papertape.

With the result that an observation of the'tape will reveal the time ofday or 'nightfwhichthe'body Was moved and. for

how long the movement -continued. My

mechanism is so arranged that the needle will make its record whetherthe hammer.

asses u ward or downward 1 ast its hori-Mi' zontal center.

Modifications may be made within the scope of the appended claimswithout departing-from the principle or sacrificing the advantagesofthis invention. An .ink pen of any approved style may be substitutedfor the pin G, or ink may be fedto the pin G, causing it to ink the edgeof the pcrfo-' ration. A carboni-or other prepared tape may pass in,parallel with the paper strip and between it and the type faces it" thisis desired metal type would be preferable to the rubber shown. I canprovide a drum for rewinding the tape after it has received,

the impression and perforations, but I .do

not consider this necessary. Other modifications may be made by a goodmechanic in the driving means, bevel-gears etc.
